论文摘要

1形式对称性和0形式对称性可以组合形成一个称为2组对称性的延伸。我们在一类Argyres-Douglas理论中发现了后者的存在,称为$ d_p($ usp $(2n))$,可以通过$ \ mathbb {z} _2 $ twisted compactification $ \ mathbb {z} _2 $ twist twist compactification the 6d $ \ mathcal {n} =(n} =(2,2,2,2,2,2,2,2,2,2,2,2,2,00完整的穿刺。我们提出了$ 3 $ d的镜子理论的一般$ d_p($ usp $(2n))$理论,这些理论是研究其风味对称性和希格斯分支的重要工具。 Yet another important result is presented: We elucidate a technique, dubbed ''bootstrap'', which generates an infinite family of $D^b_p(G)$ theories, where for a given arbitrary group $G$ and a parameter $b$, each theory in the same family has the same number of mass parameters, same number of marginal deformations, same $1$-form symmetry, and same $2$-group structure.该技术用于在几类$ d^b_p(g)$理论中建立2组对称性的存在或不存在。在这方面,我们发现$ d_p($ usp $(2n))$理论构成了具有2组对称性的特殊类别的Argyres-Douglas理论。

A 1-form symmetry and a 0-form symmetry may combine to form an extension known as the 2-group symmetry. We find the presence of the latter in a class of Argyres-Douglas theories, called $D_p($USp$(2N))$, which can be realized by $\mathbb{Z}_2$-twisted compactification of the 6d $\mathcal{N}=(2,0)$ of the $D$-type on a sphere with an irregular twisted puncture and a regular twisted full puncture. We propose the $3$d mirror theories of general $D_p($USp$(2N))$ theories that serve as an important tool to study their flavor symmetry and Higgs branch. Yet another important result is presented: We elucidate a technique, dubbed ''bootstrap'', which generates an infinite family of $D^b_p(G)$ theories, where for a given arbitrary group $G$ and a parameter $b$, each theory in the same family has the same number of mass parameters, same number of marginal deformations, same $1$-form symmetry, and same $2$-group structure. This technique is utilized to establish the presence or absence of the 2-group symmetries in several classes of $D^b_p(G)$ theories. In this regard, we find that the $D_p($USp$(2N))$ theories constitute a special class of Argyres-Douglas theories that have a 2-group symmetry.
